A web offset press includes several printing units through which a web passes essentially in a horizontal direction. The printed web then passes to at least one first folding unit. Each of the printing units has at least one plate cylinder and one transfer cylinder which interacts with the web being printed. An effective plate width of the plate cylinder corresponds to the print image of at least eight upright or prone printed pages in a BIN 4A format. The printed web is slit longitudinally into a plurality of web strands: A first number of these web strands are supplied to the first folding apparatus. At the same time, a second number of web strands, produced by the slitting of the same web, are supplied to a second folding apparatus for further processing.

A material roll is transported to a roll changer by being arranged on a transport carriage. The material roll and transport carriage are placed on a transfer table which is moved into position between journal bearings of the roll changer. The transfer table is adapted to move the material roll transversely and along a longitudinal axis of the material roll and can pivot in a horizontal plane. An inclined position of the material roll, arranged on the transfer table, is determined by sensors. In this determined, axially aligned position, the material roll is axially aligned on the bearing journals. The roll size of the material is determined. An axially aligned position for roller support arms of a roll carrier of the roll changer is determined as a function of the determined roll size. An axially aligned position of the transfer table is determined as a function of the determined roll size and the determined inclined position of the material roll. The position of both ends of the sleeve of the material roll, upon insertion of the transfer table into the roll changer, is detected. The material roll is then inclined by a rotary drive which is arranged on the transfer table.

A device is used to convey empty rolls that have been removed by at least one roll changer of a web-fed rotary printing press. At least one empty roll receptacle can be displaced between the roll changer, where the empty rolls are held by the receptacle after they are removed by the roll changer, and an emptying station where the empty rolls are removed from the receptacle. A collection receptacle is provided at the emptying station. The empty rolls are emptied from the empty roll receptacle to the collection receptacle.
